Abstract

L'invention concerne un procédé de détection d'un défaut dans un stator d'un générateur, en particulier d'un générateur synchrone d'une éolienne. Le stator comporte une pluralité de bobines de stator (S1-S5). Une source de courant (300) servant à générer un flux de courant à travers l'enroulement du générateur est raccordée. Un champ magnétique produit par des bobines de stator (S1-S5) du générateur est détecté par un moyen (400) servant à détecter un champ magnétique. Une position d'un défaut est déterminée par identification des bobines de stator (S1-S5) qui ne produisent pas de champ magnétique.
